JOHN H. MCKENZIE AND JOHN KELLER, OF VERSAILLES, KENTUCKY.

TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent N0. 278,720, dated June 5, 1883.

To all whom, it may concern Be it known that we, J OHN H. MCKENZIE and JOHN KELLER, of Versailles, lVoodford county, and State of Kentucky, have invented anew and useful Improvement in Road-Carts, of which the following is a full, clear, and eX-' act specification,reference being had to the accompanying drawings, forming part of this statement of invention, in which Figure 1 is a longitudinal section of our road-cart. Fig. 2 is an elevation of spring A. Fig. 3 is a plan of lower side of spring A. Fig. 4. is an elevation of spring D, showing attachment to cross-bar. Fig. 5 is a plan of spring D. Fig. 6 is a perspective view of spring and shaft-couplingsC and B. Fig. 7 is an elevation of shaft-coupling C. Fig. 8 is a cross-section of shaft-coupling C. Fig. 9 is an elevation of spring-coupling B. Fig. 10 is a cross-section of spring-coupling B. Fig. 11 is an elevation of seat and foot-board joint or coupling. Fig. 12 is a vertical section of seat and foot-board joint or coupling. Fig. 1 is a perspective view, showing attachment of footboard spring D to cross-bar, and showing loop H, into which spring A goes. Fig. 1 is a perspective view, showing attachment of loop for spring A to cross-bar, looking from below, and showing T- piece 1'.

Similar letters of reference drawings indicate the same parts.

Our invention relates to spring road-carts, and to that class in which the spring is not di' rectly supported by nor attached to the axle; and it consists First. In attaching a spring, A, to the seat E of a road-cart at one end by bolts, to the shaft F by a pivot, and in holding loosely the other end of the spring in a loop, H, on the cross-bar L. WVe pivot thespri'ng to the shaft in the following manner: The coupling 0, Figs. 1, 6, and 7, is bolted to the shaft, and the coupling B is bolted to the spring. Figs. 8 and 10 show sections of these couplings. It will be seen that coupling B slides onto or journals on a portion of coupling 0, and that one pivot-bolt, Z1, holds them together. The spring is thus freeto move on the bolt b.

Second. In attaching the foot-board K to the seat E by a flexible joint. or coupling, N, Figs. 1, 11, and 12, and to the crossbar L by in the several This spring D is bolted end of the spring is not confined, but is free to move in the loop as the seat is raised or lowered, the spring being free to move on the pivot-bolt b. The loop is bolted on by the same bolts that secure the T piece r, the T- piece 0' forming a rub-iron for top of spring.

The object of our invention is to make a cart on which the rider will not directly re.- ceive the jar from the axle incident to uneven roads, nor the motion of the shafts arising from the movements of the horse.

WVe hang the foot-board by a flexible joint and a recurved spring to prevent jarring to the feet, having found by experience and experiment that a rigid foot-board, or one attached .to the cross-bar by a straight spring, will not be without'such jarring.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is as follows:

1. In a road-cart, thecombination, with a seat, shafts, and cross-bar, of the springs A, secured at rear ends to the seat,loops H on the cross-bar to receive the other ends of the springs, and couplings to connect the middle portions of the springs to the shaft, consisting of portions B and O, pivoted together and se cured to their respective parts, as set forth.

2. In a road-cart, the combination, with a seat, foot-board, cross-bar, and shafts, of couplings N, consisting of rings 00 and hinge-pieces y 1 connecting foot-board to seat,- and the recurved springs D, connecting the bottom of the foot-board with the top of the cross-bar,

as set forth.

3. In a ,road-cart, the combination, with a seat, shafts, foot-board, and cross-bar, of the springs A, pivoted at their middle portions to the shafts, flexible joints N, connecting footboard to seat, and recurved springs D, connecting foot-board to cross-bar, as set forth.

4. In a road-cart, the combination of spring IOO A, and pivoted coupling consisting of portions B and C for attaching the middle part of the spring to the shaft, as set forth.

5. In aroad-cart, the combination of a spring pivoted at its middle portion to the shaft, a seat to which one end of the spring is firmly secured, and a cross-bar provided with a loop for holding loosely the other end of the spring, as set forth.

6. In a road-cart, a foot-board secured to the seat by a flexible joint and to the cross-bar by a recurved spring, as set forth.

The foregoing specification of our invention sign ed by us this 12th day of March, A. D. 1883.
